• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (thuat san)) ky nang xa hoi. hieu ve ((cac dac) OR (cac dai)) va thanh hoi cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) or (thuat san)) ky nang xa hoi. hieu ve ((cac dac) OR (cac dai)) va thanh hoi cua triet".
